Conan's reasoning ability is the best, while Blackfield Haidong is good at magic. They all have good sports cells. But Conan didn't change back to Kudo. He lacked more physical qualities than the strange thief, and Heichang Haidong had more advantages. If they were the same age and figure, they might be as resourceful and brave as Kudou Yū saku and Kuroba Touichi (the father of Haidong in Blackfield), and it is difficult to tell the result.
